Solve : Dell Deminsion will not power up? |
|
Answer» My d521 will not POWER up. If I unplug the 4 PRONG connector right at the memory SLOTS, then the power supply STARTS but the computer still will not boot. I don't know how to trouble shoot the mother board. I have new memory installedIs this occurrence happening right after you installed your new memory? truenorth Dell has no listing for a Dimension D521. I think the connector you are referring to is known as the P4 connector; it provides ADDITIONAL +12VDC to the motherboard. It's possible the power supply has failed. |
